MACHINE FOR MERCERIZING.

SPECIFICATION forming part Of Letters Patent NO. 624,800, dated May 9, 1899. Application filed February 3, 1899. Serial No. 704,413. (No model.)

T aZZ whom it. may concern.-

Be it known that I, EDUARD HEBERLEIN, chemist, a citizen of the Swiss Republic, and

' a resident of Wattwil, canton of St. Gall,

' panyiug drawings, in w-hich I Figure 1 shows a front view, and Fig. 2 a side view, of the same when not in use, While Fig. 3 shows a side view of the same when in use for impregnating yarns or threads with lye.

The machine has at bottom a rectangular frame A, on which are fixed bearing-brackets a for carrying two shafts B. On these shafts are fixed arms 19, carrying the four wheels 0, which support the entire machine on rails c, on which it can consequently be run along. On both sides of the frame A there are two upright supports DD D D, of which D D are fixed to the frame A, while the others, D

. D, are connected thereto by hinges, so that they can be turned down into a horizontal position. The fixed supports D D are stayed on the frame A by means of stays E and are fixed together at top by means of a transverse beam F of trough-section. The other two supports D D when in the vertical position are also engaged by their upper ends with the at top,

cross-beam F, which serves for their secure support. 7 For this purpose each of the supports D has at its upper end a metal plate 6, which can be pressed against the cross-beam F, so as to hold D in its vertical position by means of a pivoted latch H, taking into a hasp m, fixed to the beam F.

On the frame A are fixed bearings f, open which receive the end trunnions h of a roller I, and on the supports D are lateral projections g, which in the vertical position of the supports engage over the trunnions h, so as to prevent any vertical motion of the roller I. Above the latter is a second roller 1, the end trunnions h of which rest in the hook-shaped ends 1' of two internally-threaded slides K,through which are screwed two screwspindles L, so that by the rotation of the latter the slides will be moved upward or downward between the supportsDD. The screwspindles project up above the beam F and carry bevel pinions 7c, gearing with other bevel-pinions 0, fixed on a traverse shaft M, carried in bearings 01 on the beam F, so that onrotating the shaft M by means of a handwheel N the two screw-spindles are simultaneously rotated for raising or lowering the slides K and roller 1,

On the shafts B are fixed hand-levers P, that can be turned through ninety degrees, so that by turning the levers from the position shown in Fig. 2 into that shown in Fig. 3 the arms b, fixed on the shafts B and that carry the wheels 0, are turned from the vertical position at Figs. 1 and 2 into the horizontal posi tion, Fig. 3, and thus effect the lowering of the frame A and parts carried thereby.

Between the rails c c is arranged a tank S, containing the lye with which the yarns or threads are to be treated.

The machine is operated as follows: The yarns or threads at to be treated are laid over the rollers I I in a spread-out condition while the machine is in the raised position, the supports D having been previously turned down (the latches H being raised for this purpose, as indicated by the arrows y) and the rollers lifted out of their bearings for the above purpose. The yarns being laid on as described, the rollers are again placed in their bearings f and i and the supports D are raised into their vertical position and secured by turning the'latches H so as to engage with the hasps m. The shaft M is then turned, so as to rotate the screw-spindles in the direction 'for raising the slides K and roller I. The rollerl being prevented from rising by the projections g on the supports D, the banks of yarn will be stretched to any required degree between the rollers I I. The hand-levers P are then turned into the position at Fig. 3, so as to lower the machine, when the under side of the lower roller I will become immersed in the lye in the tank S. Upon now imparting rotation to the roller I on fitting a crank-handle on the square end if one of the trunnions h or by means of any other suitable'driving-gear the hanks of yarn will be made to travel around on the rollers, so as to be immersed in and become impregnated by the lye. After this has been sufficiently effected the machine is raised again by turning back the hand-levers P, the supports D are lowered again, and the rollers I I, together with the yarns thereon, are removed or the machine is run to a washing device for Washingformly spread-out condition.

Third. By means of the adjustable upper roller 1 yarn hanks of any size can be treated by the machine.

Fourth. When using such lyes that produce a shrinking of the fibers, the fixed position of the'rollers I I after adjustment will prevent any such shrinking.

Fifth. If the yarns are to be washed after the impregnation, this can be effected without removing them from the machine by running the machine to a washin g or rinsing apparatus, where the yarns can be washed while on the machine.

What I claim is 1. A machine for uniformly impregnating yarns or threads .of vegetable or animal fiber with caustic liquids, consisting of two rollers removably mounted one above the other on the framing of the machine, on which roll-.

ers the yarn or thread hanks are mounted, the lower roller being held in its bearings so as to be prevented from rising, while the upper roller is adjustable in a vertical direction for stretching the yarns, and means for raising and lowering the machine so that when in the lowered position the lower roller with the yarn upon it dips into caustic liquid contained in a tank below, so that on rotating one of the rollers the yarn thereon is made to travel through and become impregnated with the liquid while in a stretched condition, substantially as and for the purposes described.

2. A machine for uniformly impregnating yarns or threads of animal or vegetable fiber with caustic liquid consisting of two rollers removably mounted one above the other on the framing of the machine, on which rollers the yarn or thread hanks are mounted, the lower roller being held in its bearings so as to be prevented from rising, While the upper roller is adjustable in avertical direction for stretching the yarns, the framing of the machine being supported on wheels carried by arms that are pivotally connected to the framing and can be turned from a more or less vertical position into a horizontal position so as to lower the machine and thereby cause the lower roller with the yarn thereon to dip into' a tank containing the caustic liquid, while when the said arms are turned into the vertical position the lower roller and yarn are raised out of the liquid, substantially as described.

3. A machine for uniformly impregnating yarns and threads withfi caustic liquid consisting of two rollers refnovably mounted one above the other on the framing of the machine, on which rollers the yarn or thread hanks are mounted, the upper roller having its trunnions carried in vertically-adjustable hooks, while the 'trunnions of the lower roller are carried in bearings open at top in which they are prevented from rising by projections on vertical supports that can be turned down on pivots and are secured in the vertical position by locking-latches, a tank for containing the caustic liquid situated below the lower roller of the machine, and means for raising and lowering the machine so that the lower roller shall either dip into the liquid in the tank, or shall be raised out of it, substantially as described.

4. In a machine for impregnating yarns, the combination with the base-frame and the upright frame thereon, of the roller I, mounted rotatively in the base of said upright frame, the vertically-adjustable roller I, mounted also in said upright frame, and the means for raising and lowering said frames, said means comprising the levers P, shafts B, arms b, on the said shafts, respectively, and substantially at right angles to the levers P, and the wheels 0, carried by said arms, substantially as set forth.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses. I

EDUARD I-IEBERLEIN.
